the lubricating Y of the" connections between drive anddriven rotary members such as, for

example,and-more particularly, the loose and 5 wobbling' connections commonly employed in relatively heavy machines, asfor example, between drive-spindles and the rolls of rolling mills which are driven atu relatively slow speed, the. present application as to certain 10 fe'aturestheiveof being a division of my application for Letters Patent Serial No.

Such connections are subject vto very rapid wear, with consequentlyimpairment unless properly lubricated, due to the great rubbing action which occurs in use between the Top-f spindle and-roll, 'thereby rprovidlng, aloose posing surfacesof the connecting means.

My object is to providea novel,simple and effective means for adequatelylubricating such connecters"to-theend'of greatly pro-' longing their life"; to provide forsuch lubri eating without waste of lubricant and at a relatively low cost for labor; and to provide 1.25 for the substantially uniform supplying of the lubricant to the various interfitting drive and driven surfaces to be lubricated; and other objects as will be manifest from the following description. Referring to the accompanying drawings: Figure 1 is a View in side elevation of the adjacent ends of a drive spindle of a rolling mill and a roll to be driven thereby, together with a coupling box connecting together the 85 spindle and roll for drive of the latter from the spindle, the structure being provided with lubricating means constituting one of the embodiments of my invention.

Figure 2 is a section taken at the line 22 on Fig. 1 and viewed in the direction of the arrow.
